Hard to say. I used to use this structure as my bible but I felt some of the comparisons I was getting back were very simplistic. Basically some students were only pointing out obvious similarities but failing to comment on subtle differences between the texts. As long as you bear in mind that subtle differences matter every bit as much as similarities, you should be fine to use this structure. This example might also help (it’s cultural context rather than theme but the same basic principles apply) http:///2013/12/sample-comparative-link/
It’s as well to keep in mind what you should not be doing. Do not introduce lots of fresh evidence at this stage, though you can certainly introduce the odd extra fact that clinches your case. Nor should you go on to the ‘next’ issue. If your question is about Hitler coming to power, you should not end by giving a summary of what he did once in power. Such an irrelevant ending will fail to win marks. Remember the point about answering ‘nothing but the question’? On the other hand, it may be that some of the things Hitler did after coming to power shed valuable light on why he came to power in the first place. If you can argue this convincingly, all well and good; but don’t expect the examiner to puzzle out relevance. Examiners are not expected to think; you must make your material explicitly relevant.
The third paragraph of the body should contain the weakest argument, weakest example, weakest illustration, or an obvious follow up to the second paragraph in the body. The first sentence of this paragraph should include the reverse hook which ties in with the transitional hook at the end of the second paragraph. The topic for this paragraph should be in the first or second sentence. This topic should relate to the thesis statement in the introductory paragraph. The last sentence in this paragraph should include a transitional concluding hook that signals the reader that this is the final major point being made in this paper. This hook also leads into the last, or concluding, paragraph.
